The Buffs (15-7, 5-5) ended the game on an 8-0 run with Roberson scoring the final four points after ripping down offensive rebounds. The Ducks (18-5, 7-3) did not score over the final 4:26 and had their 24-game home win streak snapped by the visitors from Boulder.

Roberson followed his own miss with the game-winning basket to give CU its first and only lead with 29.5 seconds left.

"I didn't want to lose, and it starts with me," Roberson said after leading the Buffs with 10 points on 5-for-10 shooting and 13 rebounds (five offensive). "I just took it on myself to go out and play defense and continue to fight. We were still right there; we just weren't getting over that hump to get the lead. I tip my hat to each and every one of our guys."

Spencer Dinwiddie got a piece of E.J. Singler's final shot on the other end after Dana Altman drew up the final play for the Ducks, who have lost three consecutive games after ascending to No. 10 in the polls.

Roberson was fouled with 1.1 seconds on the clock and missed the front end of a one-and-one.

Oregon's Arsalan Kazemi grabbed the rebound but was unable to get off a shot as the final horn sounded.

It was an impressive bounce-back victory for the Buffs, who were coming off a 58-55 loss at Utah. CU trailed by 22 points in Salt Lake City before coming up just short.

"As painful and as disappointing as that Utah loss was for us, it might have done this team some good," Boyle said.

The Ducks were without starting point guard Dominic Artis, who missed his fourth consecutive game with a left-foot injury.

In the previous three games, Oregon turned the ball over 65 times. Both teams had 12 turnovers, but CU committed only four of its miscues in the second half.

Dinwiddie, who had two turnovers and no points at halftime, opened the second half by completing an And-one to get the visitors within 28-26.

The Buffs' point guard finished with eight points, four assists and two turnovers in the defensive slug fest.

After a 3-pointer by Xavier Johnson, the Buffs' deficit was one point (32-31) with 15:20 remaining.

But timely rebounds, a dunk and a transition layup from Kazemi, the Ducks' 6-7 senior transfer from Rice viaIran, kept CU at bay. Oregon had 27 second-chance points off of 16 offensive rebounds and held CU to 36.5 percent shooting.

"Playing Oregon was like a street fight. They're tough," Boyle said. "We talked about limiting them to one shot and they get (16) offensive rebounds. We just kept talking about it every timeout. But our guys got stops when they needed to."

A soaring slam by Carlos Emory (14 points) gave Oregon a 47-40 advantage. CU improved to 3-6 on the road by closing the game on an 8-0 run.

"It says that we're never going to give up. I think you saw that in the Utah game as bad as that turned out," Dinwiddie said. "It shows the toughness and the heart that this team has. Resiliency is I think the right word. We're a very resilient group."

The Ducks led 28-23 at the intermission after holding the Buffs to 33.3 percent (9-for-27) shooting.

Singler scored 12 of his 14 points before the break. The 6-6 senior forward made a 3-pointer to cap a 9-2 run that gave the Ducks a 26-19 lead.

The Buffs turned the ball over five times and yielded five offensive rebounds in the first eight minutes and fell behind 15-7.

Jeremy Adams -- who delivered two aggressive drives and a shot clock-beating 3-pointer -- sparked the Buffs off the bench after the slow start by the starters.

Askia Booker missed five of his first seven shots but connected on a deep ball to tie the score 17-17 with 5:47 left in the first half.

Josh Scott made a tough fade away shot at the buzzer to bring CU to within five points at halftime.

Roberson -- who entered the game tied with Siena's O.D. Anosike as the nation's rebounding leaders (11.6 rpg) -- was the only CU player to score in double figures. Booker and Johnson joined Dinwiddie with eight point each.
